This mod is about a popular meme in China. A man took a driving test but failed for some funny reasons. You can see this video.
This mod adds bed boats and bed minecarts. Players can ride boats and minecarts while sleeping.
And also, bed boats and bed minecarts can work similar to the beds - you can set your spawn point on them. And after you get back from the end or respawn after dying, you will find you riding on your bed vehicle. But you cannot use bed vehicles to skip the night.
Bed vehicles can also keep the chunk force loaded. So they can also be used as chunk loader, or long distance transporting other mobs like villagers, pigs and even zombified piglins.
